Abstract
Twelve morphogroups were defined on the basis of test shape and nature of test coiling as a result of the investigation of the Paleocene benthic foraminifera from the coastal part of East Stara Planina. The morphogroups are rounded trochospiral (RT), plano-convex trochospiral (PT), biconvex trochospiral (BT), milioline (M), rounded planispiral (RP), lenticular (L), flattened ovoid (FO), tapered and cylindrical (T/C), spherical (S), flattened tapered (FT), tubeshaped (T), streptospiral and heteromorphous (S/H). The previously described Byala-type and Flysh-type assemblages differ from each other by the predominant test morphology. There is no strongly dominating morphogroup in the Byala-type, while the Flysh-type is strongly dominated by two morphogroups. Both Byala-type and Flysh-type are dominated by morphogroups typical for deep sea conditions.
